ABSTRACT:
The pool filter cleaner is a device for simultaneously cleaning the interior and exterior surfaces of a conventional cylindrical pool filter. The pool filter cleaner includes first and second elongated pipes, each having an upper end and a lower end. A hose connector provides fluid connection between an external hose, the upper end of the first elongated pipe and a first end of a cross pipe. A second end of the cross pipe is in fluid communication with the upper end of the second elongated pipe. A sprinkler head is mounted on the lower end of the first elongated pipe, and a nozzle is mounted on the lower end of the second elongated pipe. A cap is slidably mounted on the first elongated pipe, the cap being adapted for covering and sealing an upper opening of the pool filter when the sprinkler head is inserted within the pool filter.
